Don't get me wrong - I think an RT4 is about as good looking as a racing car can get - but it soon became 'Formula RT4'...up until then, the shapes just weren't different, they were quite different.

A casual observer could have been excused for not being able to tell a Lotus from a Brabham from a Cooper a decade earlier - but a Modus was distinctive from a March from a RT1 from a Chevron.

Keep 'em coming!!
